Hello. I have got and installed a copy of Alias(PC). Then I got a problem at the first stage(Casino). 1.After talking to the head waitress, I got Sydney standing close to the Blood Mary. 2.When the head waitress went away and turned her face to the wall, I got the item-menue by left arrwo key. 3.Then I focused "Tracer Serum" by down arrow key. 4.And here I got the problem. I had tried the action key(B by default) before the head waitress truned he face back, but nothing happened. I'd like to know how to: 1.Dump Tracer Serum into Blood Mary. 2.Pick up the tray with Blood Mary. Finally, send best Mid-Autumn-Day wishes from China. Thanks.
